Well, after figuring out how to up scale the 1:144 scale N-1 to a massive 1:72 scale I've gone and started it
This is how I managed to upscale the 1:144 templates:
1. Print the parts sheets at 200% but as multiple page "Banner" or "Poster"
2. Cut out and join those parts that require it, such as the 1st stage engine base, etc.
3. Organise and lay down the parts onto A3 sheets, making sure I have everything identified properly
4. Scan / Copy those A3 parts sheets and print onto the 200gsm A3 Card Stock sheets I already have.
A bit fiddly but it should keep me busy until the skies clear and I can get back into some Astrophotography.
